BACKGROUND OF THE INVENTION

1. The Field of the Invention

The invention is in the field of electronic controllers for exerciseequipment. More specifically, this invention relates to a method andsystem for selective adjustment of an exercise apparatus to simulatemovement along a desired pathway.

2. The Relevant Technology

The desire to improve health and enhance cardiovascular efficiency hasincreased in recent years. This desire has been coupled with the desireto exercise in locations that are compatible with working out within alimited space such as within an individual's home or exercise gym. Thistrend has led to an increased desire for the production of exerciseequipment. Furthermore, in modern urban society, it has become more andmore difficult for the average individual to experience the exhilarationof exercising in nature. To compensate for this difficulty, athleticsports gyms and exercise facilities featuring treadmills, bicycles orexercise bicycles, weights, and stair stepper machines, have beendeveloped in great abundance.

Climbing devices have also become very popular in recent years. Climbingrequires a user to raise the user's knees in continual, strenuousstrides. Climbing typically requires more exertion than mere walking ona flat surface. Consequently, the exercise of climbing can provide amore intense, challenging workout. Climbing exercise apparatusestypically feature an endless moving assembly, which is set on asignificant angle and has a series of foot supports or steps. Thisconfiguration allows the exerciser to simulate the movements ofclimbing, walking, or running up a steep incline. Angled, movingstaircase-type devices are typical examples of such climbingapparatuses.

Unfortunately, typical climbing devices within the art are tall andoften require more ceiling height than is available in an exerciser'shome. Thus, such climbing devices generally require a gym or warehouse,or at least a vaulted ceiling. Treadmill devices that fit into a user'shome generally incline from a neutral position to an inclined position,then decline back to the neutral position. However, typical treadmilldevices fail to adequately provide a user with the kind of terrainexperience encountered when ambulating over rocky, rough, and naturalterrain. For example, a hiker traversing a hiking trail typicallyexhibits greater lateral movement than most treadmill belts presentlyallow. Furthermore, beginning at around a 15% grade, a hiker exercisingon a treadmill can start producing more energy than is necessary todrive the treadmill belt, such that a braking system is desirablyemployed. These structural, systematic requirements are presently notconsidered in the design of modern treadmills.

What is needed is a controller on an exercise apparatus that simulatesthe dynamics of natural terrain with its accompanying slopes andinclines and can fit into a user's home or another location with alimited ceiling height. Unfortunately, controllers presently associatedwith these exercise devices are only capable of creating an artificialtime based environment. Generally, these exercise devices use anindicator to demonstrate the increase in workout difficulty as atreadmill increases its inclination or a stair stepper becomes moredifficult to climb. These devices are exclusively time based, meaningthat no matter how slowly an individual is walking, after a certainamount of time, an artificial hill displayed will pass. Unfortunately,time based regulation does not accurately simulate the environment thatexists in a real hike or a real walk, depriving the individual of thesubstantial health benefits associated with a cardiovascular workoutbased substantially on a natural setting.

Exercise devices that utilize artificial mountain profiles typicallycreate mountains of speed or of incline. Usually, these artificialprofiles are time based workouts, where at a preprogrammed time in theworkout, the exercise apparatus moves a little faster or increases theresistance, and then during the next workout segment the device altersits operating parameters again. Eventually, the device works its way upto a maximum speed, maximum incline, or maximum workout. Accordingly,the artificial profile adjusts the exercise apparatus so that the nextsegment becomes less difficult or more difficult by changing theresistance, inclination, or speed. As such, the typical exercise devicegoes through pre-set profiles. However, the artificial mountain or hillsegments are simply time-based alterations of resistance, speed orinclination. Thus, typical workouts lack the natural diversity providedby a mountain trail.

The natural diversity provided by mountain trails yields additionalincentives for a user to complete a workout. Representative exercisedevices lack these incentives when their workouts are based purely onartificial workout profiles.

Finally, users of existing climbing exercise devices are increasinglyfaced with the difficulty of interpreting multiple monitoring panelswith a single glance during the workout, resulting in sensory overloadfor the user. Most controllers contain separate indicators for distancetraveled, vertical feet traversed, remaining workout length, andrelative grade or incline adjustments to be made. It is difficult for auser to interpret and understand all of these gauges with one glance.

SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide a method andsystem that electronically simulates a mountain hike.

It is another object of this invention to provide a method and systemfor converting a topographical map to an actual exercise workout for usewith an exercise device that can vary between a variety of grades.

It is a further object of the invention to allow the user directadjustment control of grade and speed, as well as tracking vertical feethiked and the overall distance and speed.

It is a further object of the invention to provide exercise devices suchas hiking apparatuses, climbers, treadmills, exercise bicycles, skiers,aerobic ellipticals, rowing devices, steppers and other devices that cansimulate mountain trails, mountain streams, or rough terrain through anadjustment in resistance, incline, or speed.

It is another object of the invention to provide a controller whichcontrols a workout that is both time and distance based, therebyallowing an individual to hike at their own pace and ensuring that theyadequately follow a realistic mountain trail length.

It is another object of the invention to provide a single glance panelcontaining graphic representations because the user is only be minimallydistracted from a workout.

It is another object of the invention to provide a carefully designedgraphical representation panel allowing the user to obtain all of theimportant information with one glance.

These and other objects of the invention, as will be apparent herein,are accomplished by generating a mountain exercise profile having trailworkout segments that are digitally coded to enable a selectivelyadjustable exercise device. A selectively adjustable exercise systemcomprises a virtual trail system for use on a selectively adjustableexercise apparatus.

Aside from being electrically coupled to the selectively adjustableexercise device and a display device, a controller of the virtual trailsystem operates according to software based workout profiles. Thesoftware interprets feedback from the exercise device and a userinterface console to generate control signals for motors, electronicbraking systems, and user monitors associated with the virtual trailsystem. The control signals for the exercise device components anddisplay device panels are compiled into workout profiles for use by thecontroller. Other features of the exercise system include theincorporation of direct adjustment keypads on the user interface consolefor grade and speed settings. These keypads are primarily used when thesystem is not recalling a preprogrammed workout routine or hiking trailand is under manual control.

These and other objects and features of the present invention will bemore fully apparent from the following description and appended claims,or may be learned by the practice of the invention as set forth herein.

Understanding that these drawings depict only typicalembodiments of the invention and are not therefore to be considered tobe limiting of its scope, the invention will be described and explainedwith additional specificity and detail through the use of theaccompanying drawings in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention is described below by using diagrams to illustrate eitherthe structure or processing of embodiments used to implement the systemsand methods of the present invention. Using the diagrams in this mannerto present the invention should not be construed as limiting of itsscope. The present invention contemplates both methods and systems forselective adjustment of exercise equipment.

One embodiment of a virtual trail system of the present inventioncomprises: (i) an interface means for receiving workout related controlinputs from the user of the exercise equipment; (ii) processor means forelectronically computing operational information based at least on parton control inputs received from the interface means; (iii) feedbackmeans for conveying information concerning the amount of exerciseperformed by the user to the processor means; (iv) indicator means fordisplaying workout information to the user adapted for indexing travelalong the length of a workout trail from segment checkpoint to segmentcheckpoint until the end of the trail; and, preferably, (v) controlmeans associated with the processor means for causing the indicatormeans in response to information from the feedback means to travel alongthe workout trail at a rate proportional to the rate of which exerciseis performed by the user.

This virtual trail system may be used in a wide variety of selectivelyadjustable exercise equipment. For example, in one embodiment asdepicted in FIG. 1, the virtual trail system is associated with a hikingexercise apparatus. The virtual trail system may also be employed onvariety of other hiking exercise apparatuses, such as those identifiedin U.S. patent application to Cutler, et al entitled “Hiking ExerciseApparatus,” filed on Feb. 2, 2000, which is incorporated herein in itsentirety by reference.

In addition to treadmills, alternative embodiments include associatingthe virtual trail system with an exercise cycle, an elliptical aerobicapparatus, a stair stepper, a skiing device, rowing equipment, and otherexercise devices, can also simulate mountain trails, mountain streams,or rough terrain. Each of these exercise equipment embodiments wouldrequire unique components as previously designated to provide thenecessary adjustment in resistance, incline, or speed. However, many ofthe embodiments contain considerable crossover for their respectiveapplications.

For example, an exercise cycle can very easily use a mountain bikingtrail to create a similar experience as a hiker might experience on atreadmill or stair stepper. One difference in the hiker and bicycleembodiments would be that the exercise cycle can either increase theresistance or physically move the exercise cycle in an up and downfashion.

An embodiment based on a skiing device can use mountain cross-countryski trails and either adjust actual grade or alter the resistance. Arowing device can simulate mountain streams or rivers by adjustingrowing resistance or restricting the rowing action.

The mountain exercise profile may use topical maps, GPS coordinates, orportable monitors to design the actual exercise program. A trail workoutdesigner can plot a trail over a mountain area on a topographical mapand a profile of the incline changes over the terrain will be created.Workout segments can be created which average the slope change for thatdistance, resulting in multiple grade changes according to the trailsegment.

In FIG. 2, examples of such workout segments are designated as the trailbetween the alphabetical markers on each trail. An alternativeembodiment allows for workout segments to be subdivided for multiplegrade adjustments. These workout segments are combined into a workoutprofile. Following a review of the workout profile by a trainer, thetrail workout designer will be able to identify the density of thetrails and alter the workout segment lengths in order to fit a similartrail workout on to the specified exercise device. Specifically, thetrail workout designer creates variable segment lengths that bestcompare to the natural hike, including gradual incline segments, shortsteep segments, and short negative grade segments. A trail workoutdesigner can also use GPS coordinates in conjunction with a mastertopographical map to create a successful workout trail. Midway or restpoints may also be incorporated into a workout trail at the end of aworkout segment.

Monitor devices enable a hiker to carry the monitor on an actual hikeand record the distance and inclination walked by the user, and thenapply that particular hike to the exercise machine software. This allowsthe user to exercise on weather prohibitive days (rain, snow, or extremeheat) in which the weather does not allow a user to go outside. The usercan hike the same virtual path that they normally would take. Portablemonitors also allow a user to record their favorite workout by walkingthe trail with the monitor on. Upon electrically coupling the monitor tothe exercise system, the monitored activity can be downloaded to thevirtual trail system attached to the exercise apparatus. The virtualtrail system converts the monitored information into a workout for theexercise device. This provides the user with some exciting new benefits.For example, if it rains or snows, a user can follow their favorite hikeor mountain bike trail on an exercise bike, even if there is too muchrain or snow on the ground.

There are multiple methods of coding the hiking trail or hiking profile.The most prevalent and preferred embodiment is a translation of atopographical map into a workout and onto a hard coded copy of amountain. The hard coded copy may be stored on an ASIC chip, aprogrammable ROM, a magnetic disk, PCMCIA card, or Compaq flash card.More specifically, the software is stored in a memory module that may beupgraded with new mountain trails or workouts. This memory module may beconstructed from at least one of programmable ROM, Dynamic Memory,EEPROM, flash bios, PCMCIA cards, CD-ROM, RAM, magnetic storage disks,and Compaq flash cards. The exercise system may also provide the memorymodule through an electrical connection to a general-purpose computer.It may also be downloaded from an Internet site such as www.iFit.comacross a communication line connection, for example via the PSTN, DSL,G-Lite, cable modem, wireless or other high-speed data connection.Particularly as the cost of wireless technology drops, a wirelessconnection to exercise profile sites such as iFit.com is alsoforeseeable.

Hiking profile coding also provides the additional advantage ofrecording a hike that a user might not be able to accomplish in oneexercise session, especially if it is an all-day or multiple day hike.Since the average workout session lasts between about 15 minutes and 1hour, a user would not complete longer hikes without positional cursorstorage. However, the virtual trail system optionally saves the locationof the user, so that upon their return to the exercise system, they areable to begin their workout where they last left off. Thus, a daylonghike of eight hours might take an individual one or two weeks tocomplete at thirty-minute intervals. However, the individual would havecovered the same exact terrain as was covered in the original walk. Inthis sense, the exercise system is able to provide a user with long-termphysical goals and related incentives inspiring follow-up workoutsessions. This natural variety and follow-up incentive are importantkeys to keeping the user on a regular exercise plan.

One of the features in this invention is the interface between thedisplay device, the controller, the adjustable exercise device, andpossibly additional software. In a preferred embodiment the software isupgradeable and Internet capable. The display device is convenientlylocated on the exercise device or is optionally separate therefrom, suchas a wall mounted or hand-held display, and provides indicator signals.Thus, the display device may be physically located on the exercisedevice, but may be separate therefrom in another embodiment. Thecontroller creates codes for the display device and adjustment codes forthe exercise device. The exercise device is preferably adjustable. Theexercise device may act as a flat treadmill, hiker, or stepper, forexample. What distinguishes this exercise system from other systems isthat the user has direct control of the speed and grade. In someembodiments the system may control speed and grade during workoutroutines. The present invention differs from other devices, whichfeature time-based workouts, whereas this device uses distance-basedworkouts.

The display device is an example of an indicator means for displayingworkout information to the user and should be positioned so that a usermay easily interface with the controller and observe their progress inseveral categories of performance. An adjustable attachment is preferredso that users of varying sizes will have equivalent visual access. Inconsidering construction factors such as reliability, cost, andperformance, a liquid crystal display (LCD) provides the greatestflexibility for the display device. Other acceptable indicator meansinclude LED displays, video monitors, color LCD, and flat LCD videoscreens. Each of these visual indicator means can be varied usingcolors, brightness, or synchronized pulses to represent various statusconditions. Typically, the indicator means is a visual indicator, butauditory and tactile indicators may also be used as indicator means.Audio indicators may generate a full spectrum of audible noises,including music, chirping, beeping, continuous tone, or a specificaudible message. Tactile indicators include vibration, texturealteration, electric tingle, generation of specific Braille characters,or the creation of a temperature variation.

FIG. 2 provides an example of a preferred embodiment of implementing theinvention. This should not be seen as a limitation, however, on thearrangement or construction of the exercise apparatus. For example, inone embodiment, an LCD is employed to display clips from the actual hikeor workout trail, instead of a topographical display screen.

The controller may be a microcontroller, a central processing unit(CPU), a state machine, a programmable logic array, or network oflogical gates, ASIC processor, software-based controller, a combinationof these components, or a variety of other controllers. Each of thesecontroller examples are examples of processor means for electronicallycomputing operational information based at least in part on controlinputs received from the interface means. The controller receivesfeedback signals from the exercise apparatus and the workout profile andconverts the feedback signals into control signals for the displaydevice and exercise apparatus. Data for the controller may be stored inregisters or memory modules. The controller makes adjustments to theexercise device simulating mountainous terrain. In one embodiment, thecontroller includes a temporary storage media for use with the displaymeans. The temporary storage media provides a buffer for each of thedisplayed values, such as user age, maximum pulse and heart rate,average pulse and heart rate, target heart rate, calories burned andtarget calories to burn during workout session, length of workoutsession, and other displayed values. This multi-buffer system allows forthe simple control and rapid refresh of the user workout data.

With reference now to FIG. 1, a selectively inclining and decliningclimbing exercise apparatus 10 of the present invention is shown.Exercise apparatus 10 supports a user ambulating thereon. Selectivelyinclining and declining apparatus 10 comprises a support base 12, atreadbase 14, and a handrail assembly 16. A variety of other examples ofselectively inclining and declining hiking exercise apparatuses such asapparatus 10 to be employed in the present invention are disclosed inU.S. patent application Ser. No. 09/496,569 to Cutler, et al entitled“Hiking Exercise Apparatus,” filed on Feb. 2, 2000, now U.S. Pat. No.6,761,667, which is incorporated herein in its entirety by reference.

In a neutral position, treadbase 14 is parallel to a support surface.Treadbase 14 is capable of inclining to extreme angles, such that adistal end is high above the neutral position. This enables an exerciserto simulate a hiking motion that requires the user to continually liftthe user's knees in an upward, outstretched manner. Treadbase 14 alsodeclines such that a distal end thereof drops below the neutralposition. Typical hikes in the mountains, for example, involve inclinesand declines as well as flat surfaces. Thus, apparatus 10 is able tomore closely simulate a typical mountainous terrain. A hiker traversinga hiking trail typically exhibits substantial lateral movement. Thus,treadbase 14 preferably has an aspect ratio featuring a wide treadbase14. Examples of such aspect ratios are disclosed in the U.S. patentapplication to Cutler, et al entitled “Hiking Exercise Apparatus,” filedon Feb. 2, 2000, which is incorporated herein in its entirety byreference as indicated above.

The coupling of treadbase 14 and the positioning of handrail assembly 16may occur in a variety of different positions depending upon theembodiment. In the embodiment of FIG. 1, treadbase 14 is pivotallycoupled at the proximal end thereof to the proximal end of support base12. Support base 12 rests on a support surface. In the embodiment ofFIG. 1, treadbase 14 comprises a treadbase frame, first and secondrollers (only one roller shown) on opposite ends of the treadbase frame,and an endless belt movably mounted on the rollers.

In one embodiment, treadbase 14 is selectively moved into a positionhaving a grade of about −30% (declined) with respect to the neutralposition to about 90 degrees (inclined) with respect to the neutralposition, preferably having a grade of about −120% (declined) withrespect to the neutral position to about 60 degrees (inclined) withrespect to the neutral position, more preferably, having a grade ofabout −10% with respect to the neutral position to about 100% (45degrees) with respect to the neutral position, more preferably, having agrade of about −10% with respect to the neutral position to about 60%with respect to the neutral position. In another embodiment, treadbase14 is selectively moved into a position having a grade of about −5% withrespect to the neutral position to about 50% or 60% with respect to theneutral position.

However, these ranges are generally more of a physical limitation thanan electronic limitation as the console 200 for the exercise apparatuscan be configured in one embodiment to provide negative 360 degrees topositive 360-degree rotation.

By moving between these extreme ranges, an exerciser is able to simulatea hike through a variety of different slopes and angles. The virtualtrail system includes an electronic console 200. Console 200 iselectrically coupled to the inclination motor 18. The virtual trailsystem controls the amount of inclination/declination during eachsegment. Through the use of console 200, the user can control the amountof inclination/declination of treadbase 14, the speed of the endlessbelt and a variety of other features related to apparatus 10.

In one embodiment, the exercise system includes braking means forelectronically slowing the speed of the operable member, such as anelectronic braking system. When the exercise device exceeds a variableincline level, established by the weight of the user and the inherentresistance of the system, the force exerted on the motor of the exerciseapparatus exceeds the force generated by the motor to drive the operablemember of the apparatus and the electronic braking system should beactivated. For hiking devices, this variable incline level can occur atapproximately 15%, depending on the inherent system resistance and theforces exerted by the user. At this grade, the energy generated by theuser ambulating on the exercise device exceeds the power required todrive the motor on the operable member. At inclines above about 15% thepower generated by the virtual trail system exceeds approximately 100Watts, requiring the braking means to dissipate the excess powergenerated by the virtual trail system. In one embodiment, the brakingmeans of the present invention dissipates excess power generated by thevirtual trail system when the power generated by the system exceedsapproximately 100 Watts to approximately 700 Watts. Certain usersambulating at extreme incline settings generate excess power in therange of 500 to 700 Watts for example, depending on user and treadmillspecifications.

Therefore in the preferred embodiment, the presence of excess poweractivates the electronic braking system, which dissipates the excesspower and maintains the appropriate speed of the operable member. Onemethod of reducing this excess power is through a feedback loopconnected to the power supply for the motor, in essence reducing thepower available to the motor and slowing the belt. Another method sensesthe presence of excess power and activates the electronic braking systemby closing a switch between the motor and a power resistor, such as aheating coil resistor. This method effectively allows the motor togenerate more power, but absorbs excess power via the power resistor inthe required range of about 100 to about 700 watts, e.g. about 500 toabout 700 watts. In one embodiment, a heating coil is provided toprovide inexpensive power dissipation. However, care must be taken todisperse the heat generated by high energy levels.

In the preferred embodiment, a device cutoff system within theelectronic braking system activates a forced ventilation system whenheat levels begin to exceed pre-established operating ranges and inextreme cases completely cutoff the treadmill system until the detectedheat levels returned to safe operating ranges. Generally, the powerresistor circuit employed in the exercise device is system specific, anddesigned to dissipate excess power generated by the motor during toprolonged use at extreme inclines. Once the power is dissipated, thevirtual trail system will open the circuit between the motor and thepower resistor. In this manner the virtual trail system is able tomaintain a constant speed for the operable member at high speed and highinclination settings.

Other examples of braking systems are disclosed in the U.S. patentapplication “Hiking Exerciser Apparatus,” incorporated herein byreference.

As mentioned above, the aspect ratio, i.e., the length and width oftreadbase 14 is such that climbing apparatus 10 simulates a climbingmotion and allows the user the lateral movement associated therewith,yet has a minimal footprint and can be conveniently used and stored in ahome or exercise gym.

Handrail assembly 16 will now be discussed in additional detail withreference to FIG. 1. The handrail assembly 16 of the present inventioncan be comprised of a variety of different members and have a variety ofdifferent configurations, such as those featured presently in the art.Handrail assembly 16 of FIG. 1 is coupled to the treadbase 14 such thatthe position of handrail assembly 16 adjusts automatically throughoutthe range of motion of treadbase 14. Thus, handrail assembly 16 isuseful to the exerciser throughout the range of motion. Handrailassembly 16 has an operative, useful position regardless of whethertreadbase 14 is in an inclined, declined, or neutral position. However,a fixed handrail assembly may also be employed which does not providesuch adjustment. Handrail assembly 16 may also contain components of thefeedback circuitry for monitoring the users heart rate through thephysical connection created by the user's hold on the handrail assembly16.

In the embodiment of FIG. 1, inclination motor 18, which controls theamount of inclination/declination during each segment, is part ofhandrail assembly 16. Handrail assembly 16 is pivotally coupled totreadbase 14 and to support base 12. Motor 18 selectively inclines anddeclines assembly 16, thereby selectively inclining and decliningtreadbase 14. However, in other embodiments, such as described in U.S.patent application to Cutler, et al entitled “Hiking ExerciseApparatus,” filed on Feb. 2, 2000, which is incorporated herein in itsentirety by reference as indicated above, an extension motor or othermeans for selectively moving the treadbase is directly coupled betweenthe treadbase and the support base or coupled thereto in a variety ofother fashions.

With reference to FIG. 2, a user console 200 contains a display device202 and a control interface 218. Display device 202 is an example of anindicator means. Control interface 218 is an example of an interfacemeans for receiving workout related control inputs. Display device 202contains various workout diagnostic panels. In another embodiment of auser console, the display device of the console is located remotely fromthe exercise apparatus. For example, the display device may comprise awall mounted or hand held display.

Trail workout panel 204 displays trail workout information on one panelof said user interface console 200, the trail workout informationcomprising at least one of: percentage of trail workout completion,relative trail elevation, distance traveled, vertical distance traveled,workout segment difficulty, remaining segment length, selected trailworkout routine, and topographical information concerning the trailworkout profile. In one embodiment, each of these features are present.This single glance panel provides an optimal amount of workoutinformation to the user without distracting the user from the workout.Grade program control panel 206 includes an incline display representingthe inclination of the treadmill or exercise device in degrees or gradepercentage. In the embodiment of FIG. 2, the incline, terrain, or hillvaries from −5% to 60% grades or −5 to 32 degrees of angular movement onthe grade program control panel 206. The grade program control panel 206may contain a terrain or hill display array that is constructed from aselectively illuminated LED display array.

The virtual trail system causes the exercise device to incline thetreadbase grade or increase resistance so as to correspond to the hillsdisplayed on the grade program control terrain display. In this manner,the user is provided with a short-term display of upcoming and/orcurrent terrain. The grade program control panel 206 also contains amanual control indicator to signify that the user is establishing gradesettings. Grade program control panel 206 further comprises a data fieldshown in FIG. 2 to have 21 columns with 10 indicators in each column.Although primarily configured to indicate short-term grade settings,this array of indicators may also be used to indicate any number ofdifferent parameters. For example, the grade changes can be attached toindicate speed changes. The preferred display panel configuration takesgrade changes or resistance changes that are pending during the workoutprogram and shows the changes graphically. In FIG. 2, the second tobottom horizontal row of the grade program control panel 206 would beregarded as zero, with the number of vertical blocks being illuminatedto show the relative incline, grade, speed, or other value depicted.This array can be expanded to include more accuracy concerning the gradeor angled inclination. As the capabilities of the exercise equipmentprocessor increase, the display scale can be shifted.

A hike exertion panel 208 provides a single row of colored indicatorLEDs summarizing the workout stress level placed upon the user. The hikeexertion panel 208 divides the colored indicator LEDs into foursubcategories: warm-up/cool-down, moderate hike, challenging hike, andExtreme hike. The subcategories are either based upon preprogrammedvalues for grade level independent of the user's response to the systemand speed level or the indicator panel 208 can be a compilation andsummarization of indicator panels 204, 206, 210, 212, 214, and 216adapted to each user. In this second configuration, the hike exertionpanel 208 becomes a single look pacing indicator panel considering age,heart rate, speed, grade, pace, and hike ranking. As such the hikeexertion panel 208 is at least indirectly connected to the feedbackcircuitry, which measures the performance of the exercise equipmentand/or the user.

The heart rate training zone indicator panel 210 selectively indicatesage, heart rate and percentage of maximum heart rate of the user that isexercising. Training zone indicators show a user whether the currentworkout is proceeding above, below, or at the target heart rate for theuser's age. The pulse sensor is activated after the user enters theirage before the workout begins using the incremental adjustment keypad240. In the preferred embodiment, the virtual trail system will remembera user's vitals after they renew a previous workout. Heart rate trainingzone indicator 210 is an extremely useful feature as it allows the trailworkout to be personalized for each user, assuring that a maximumcardiovascular workout is obtained. Optional safety features in thevirtual trail system include a monitor of a user's heart rate thatreduces the stress or exertion levels imposed upon the user when theheart rate exceeds the target value. The stress level may be increasedfor a user whose heart rate is at or below the target level. These heartrate signals are received at least indirectly from the user feedbackcircuitry, part of the feedback means, which may collect informationfrom a heart monitor worn, by the user or a heart monitor placed inhandrail assembly 16.

Time and distance indicator panel 212 indicate the distance traveled orthe segment time required for the user to travel between exerciseworkout segments, or the overall time required for the trail workout.Indicator panel 214 selectively provides the vertical feet traveled, thecalories burned, the percentage of grade, and the maximum percentage.The time and distance indicator panel 212 and the indicator panel 214are at least indirectly attached to feedback circuitry connected to theexercise device. Speed indicator panel 216 provides the speed presentlytraveled on the exercise device, or the maximum speed attained duringthe exercise period. The speed indicator panel 216 is indirectlyattached to the feedback circuitry on the exercise device and morespecifically to circuitry connected to the electronic braking systemused to regulate the belt speed on the treadbase.

Control interface 218 comprises several individual adjustment keypadsfor interfacing with the selectively adjustable exercise apparatus.Direct grade adjustment keypad 220 allows the user to select a desiredgrade of an operable member of the selectively adjustable exerciseapparatus through quick touch keys with pre-set percentage grade valuesand automatically adjust the device to the selected level. Specifically,direct grade adjustment keypad 220 has pre-set percentage grade keys for−5%, 0%, 10%, 20%, 30%, 40%, 50%, and 60%, for example, although avariety of different grades are available. The grade program controllermay increase the grade or residence depending on the exercise deviceattached to the grade program controller. For example, a treadmill canincrease the inclination of the treadbase to the desired grade. Abicycle exercise device can increase the resistance such that acomparable grade is represented. A skiing device can elevate the slopeof the surface being skied upon. Similar grade or resistance adjustmentscan be made for other exercise devices. Inclination and declinationinterface buttons are also included in the direct grade adjustmentkeypad 220. These keys allow a user to increase or decrease the grade in1% grade intervals, for example.

Start interface button 224 allows a user to begin the trail workout oncethe trail has been selected or the previous segment has been restored.Stop/Pause interface button 226 allows a user to stop or pause theworkout and save the location of the user's last position on the trailfor future use or allows the user to recover from overexertion. In oneembodiment, Stop/Pause interface button 226 is electronically connectedto an electronic braking system that prevents a user from driving thetreadbase faster than the speed driven by a motor, but also for slowingthe treadbase down to a stopped position so that the user won't fall ofthe treadbase.

As mentioned above, beginning at around a 15% grade, a hiker exercisingon a treadmill may start producing more energy than is necessary todrive the treadmill belt. Thus the braking system of the presentinvention is useful at inclines such as in excess of about 15% grade andis particularly useful at high inclines, such as in excess of about 25%grade. The electronic braking system is electronically connected to thefeedback means for calculating the actual belt speed of a giventreadbase. The feedback means sends this information to the processormeans for further adjustment of the treadbase to optimize to overallperformance of the climbing exercise device.

Power indicators 228 show whether the proper activation key has beenprovided to the selectively adjustable exercise apparatus. In oneembodiment, the activation key is a physical electronic key that storesthe users workout information. Other embodiments may require anelectronic key or password be typed in so that the workout informationcan be restored from a user database. Another embodiment uses a physicalkey as a safety measure to prevent unauthorized use of the trailexercise apparatus.

Direct speed adjustment keypad 222 allows the user to adjust the speedof the particular exercise device. Specifically, direct speed adjustmentkeypad 222 has keys for 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0 and 6.0 mph.In addition to the aforementioned preset speed values, increase anddecrease buttons increase or decrease the selectively adjustableexercise apparatus operable member speed in 1/10^(th) intervals. In thepreferred treadmill configuration, the treadbase will gradually increasethe belt speed according to the inputs from the user interface console200.

Incremental adjustment keypad 240 contains an increment and decrementinput keys as well as a final enter input key. One embodiment allows auser to input their age through this keypad so that the virtual trailsystem can customize a workout and monitoring system. Another embodimentallows a user to use this keypad to enter one or more of the followingworkout variables: the exerciser's age, length of workout segment,distance of workout segment, vertical feet of workout segment, maximumspeed of workout segment, maximum pulse, target heart rate, maximumgrade, calories to be burned, and maximum heart rate. These keys mayalso be used along with the trail workout panel to specifically select aworkout segment for making adjustments in the present workout profile oreven to select different trails. For example, the virtual trail systemof FIG. 2 displays the Grand Teton trails and it is foreseeable thatvarious popular mountain recreation areas like Mt. McKinley, Mt. Rainer,Mt. Hood, the Swiss Alps, the Ozark or Allegheny Mountains, or Mt.Everest hiking layouts can be imposed in the trail workout panel 204using the incremental adjustment keypad 240.

The total input key 242 changes the display panels 210, 212, 214 and 216to display their total or maximum changes. Thus an individual is enabledto see the total distance traveled, the total time of the workout, thetotal vertical feet traveled, the total calories burned, the averagegrade, and the maximum percentage. The average speed can also beindicated through the total button. In one embodiment, the resultsdisplayed when total input key 242 is pressed, are computed usingregisters which increment the values for the time and distance, verticalfeet, and calories burned during the workout profile at variable ratesdepending on the amount of exercise and the speed of exercise beingperformed by the user. These figures are dictated by the deviceparameters. For example, the distance traveled in the preferredtreadmill embodiment is based upon the speed of the belt on the treadbase, and the distance covered by a user running upon such a base. Thetotal calories burned would be based on the angle or the grade of thetread base and the speed of the tread base. Another embodiment includesthe monitored heart rate of the individual working on the treadmill as avariable to compute the calories burned.

The select trail keypad 238 allows a user to choose a moderate,challenging, or extreme trail for their workout. In the preferredembodiment provided in FIG. 2, these trails are represented by theTeepee Glacier trail 234 as a moderate trail with workout segments Athrough G. The challenging trail is the Avalanche Canyon trail 230 withworkout segments H through P. And the extreme trail is the Grand Tetontrail 232 with workout segments R through Z. Upon choosing an exertionlevel, the workout will proceed along the workout segments until thetrail end is obtained. These end points for the trails are representedby 236 a, 236 b, and 236 c. In an alternative embodiment, a user canselect their trail exertion level using a touch sensitive trail workoutpanel 204. In such an embodiment an individual can simply select asegment letter by pushing that letter or the general vicinity of thatletter, and the exercise apparatus would adjust the settings tocorrespond to that portion or segment of the workout. It is alsoenvisioned that various embodiments would contain trails that containedmoderate, challenging, and extreme trail segments within one workout.

The iFit.com button 244 is both a selector and an indicator. Theindicator light on the iFit.com button 244 demonstrates that aconnection has been established between the virtual trail system and theexternal iFit.com system. The virtual trail system, if properlyconnected to either a computer or directly to the Internet through acommunication line connection will use software to contact the newwww.iFit.com website to obtain the services of a personal trainer.Examples of suitable communication line connections include via PSTN,DSL, G-Lite, cable modem, wireless, WAN line, radio frequencytransmission, or other data connection. Once the user initiates theiFit.com session via the interface by depressing the iFit.com button244, the virtual trail system interacts with the website to obtaindigital signals for the workout session. If the online iFit.com trainercreates a “hill climb” workout for the user, the incline of thetreadbase 14 will get steeper and steeper responsive to the personaltrainer. The iFit.com module uses a “plug in and logon” design to makeit very user friendly, even for users that are newcomers to theInternet. One advantage of the iFit.com technology is its simplicity;all the user needs to do is plug the iFit.com compatible fitnessequipment into their computer, an Internet access point or PSTN accessline. Once the connection is established, the workout options areendless. For example, the user can select a daily iFit workout, press“start,” and the virtual trail system will begin following the dailyworkout profile received from the offsite database.

An alternative embodiment allows the user to participate in a liveonline workout session. The user designates their fitness equipment andselects a personal trainer. The trainer can adjust the equipmentsettings to constantly challenge the user while monitoring the user'svitals, despite the fact that the user is working out in the privacy andconvenience of the user's own home. It is well known by those skilled inthe art that a personal trainer helps keep a user motivated, makes theuser more accountable to their goals, and helps the user achieve betterresults. The problem is, millions of consumers do not belong to healthclubs and therefore do not have access to qualified personal trainers.Use of the iFit.com button 244 provides a new standard of fitness athome. User's can schedule a private workout session with a personaltrainer conducted and monitored via computer cameras and simultaneouslysent by the trainer digital signals that control the treadmill'selectronic functions. As such, the present invention becomes a trulyinteractive personal training experience.

The iFit.com connection uses Internet “streaming” technology. Allowingconsumers to quickly select and immediately begin using a workoutsegment without downloading the entire workout profile. The iFit.comstreamable workouts are convenient and easily accessed. Furthermore, thequality of personalized workout sessions are improved, because ACEcertified personal trainers develop the workouts that are sent acrossthe iFit.com communication lines. Three predominant features are givento the present invention through the iFit.com button 244. The first isaccess to the basic iFit.com workout database that allows the user tochange his or her workout routine every day, thereby encouraging siteand workout “stickiness.” The workout database streams into the user'shome computer or exercise device and gives the user access to anelectronic library of hundreds of preprogrammed workouts whereas mosttreadmills have a maximum of only 6-8 basic workouts. For example, userscan adjust their treadmills to accommodate a specialized preprogrammed20-minute fat burning workout or an 18-minute strength-training workout.

The second area of expansion are audio workouts, which give the consumera motivating combination of heart rate paced music and the encouragingvoice of a personal trainer. Digital signals in the soundtrack control:resistance, speed, and incline of the fitness equipment. The user willbe able to choose from a variety of musical styles and enjoy them withinthe confines of their home workout area.

Finally, video workouts will stream to the virtual trail system in twocategories. The first workouts are group classes and the second arehiking adventure series trails. Both types of workouts feature heartrate paced music and digital signals to control the exercise equipment.In the group class video, users will watch a fun group “sweating it up”with a motivating personal trainer leading the workout. The adventureseries of workouts will combine music, digital signals, and add engagingscenes of natural beauty. One series features three hikes in the GrandTetons. Another running adventure series will be a workout following therace course of the St. George Marathon in St. George, Utah, named byRunner's World as the most scenic marathon in America. In this manner,the hiker treadmill can be programmed to include training workouts suchas the incline and distances of activities like the St. George Marathon.This would allow hiker treadmill users to practice for a marathon inanother state without requiring them to travel to the location to runthe course and, in essence, prepare themselves for the eventualcompetition without being there. While the functionality of the iFit.combutton 244 is presently limited to controlling the treadmill, in theforeseeable future such workouts will interact with home stereos, TVs,VCRs, DVDs, and CDs along with the treadmill to improve the quality ofthe interactive feel of the exercise equipment.

One embodiment of the hiker treadmill allows the virtual trail system tointerface with a program that emulates a particular climb. The programwill provide virtual trail system with adjustment codes that allow thehiker device to simulate the terrain of a given hike. One method ofprogramming a hike is through analysis of the GPS coordinates for astarting point, one or more weigh points, and an ending point. Thevirtual trail system will then automatically compute the distances,inclines, to simulate a hike along that course.

FIG. 3 is a control diagram for a virtual trail system with trailworkout incentives incorporated into the motivational display console onan exercise device. At conditional action block 300 a user may activatethe machine through the insertion or input of an access key. Selectionblock 305 determines whether the user desires manual or trail basedworkout control. If the user desires manual control, workout parametersmay be established by direct adjustment keypads for grade and speed,while variable keypads may provide calorie, heart rate or other workoutrelated restrictions. If trail based control is selected, executionblock 310 will identify the user and restore the last trail position forthat user. This information may be encoded into the access key or may bestored in memory relevant to the individual user. If there is noprevious workout information, the user will be placed at the beginningof a trail. Decision block 315 determines whether the trail featurebutton has been selected. If the trail feature button has been selected,the available workout trails will cycle through and allow the user toselect and adjust various trail features for the user's workout. Theseadjustments occur in execution block 325. If the trail feature buttonhas not been selected, the workout will begin from the last trailposition recorded according to the settings at that point. At startpoint 320, a conditional execution block, a user may activate themachine by pressing start. Once the exercise device starts, executionblock 330 allows adjustments to inclination and speed to be madeaccording to the workout trail program until a trail feature button isselected. If a trail feature button, as demonstrated by decision block335 is selected, then the user is allowed to adjust, modify and monitorvarious trail features in execution block 340. These features includebut are not limited to trail elevation change, trail distance, segmentdistance, segment vertical change, overall target difficulty for trailand segment, and incline or speed adjustments. Once these trail featureshave been adjusted, execution block 345 overrides the standard segmentsettings with the modified values provided in execution block 340.Generally this override occurs upon the depression of the enter button240 or the start key 224. The controller then returns to the adjustincline and speed execution block 330 and continues with the workoutsegment. Upon completion of the workout segment, a stop exercise andstore segment location command is executed in execution block 360. Ifthe trail features are not manually adjusted in decision block 335,decision block 350 checks to see if the end of the workout segment hasbeen reached. If this end point has not been obtained, the workoutprogram returns the controller to the adjust inclination and speedexecution block 330.

FIG. 4 is a block diagram illustrating the process of encoding amountain trail, the creation of a workout profile, and the standardoperation of a previously encoded hike. Execution block 400 instructs anautomated controller or a trail designer to collect trail dataconcerning the workout profile selected by the user. This data structureis comprised of various elements including a topographical informationdata string represented by block 405 a programmed routine represented by410, an iFit.com program represented by block 415, a hike simulationrepresented by 420 and a hike recreation represented by 430. Thetopographical information data structure 405 might include GPScoordinates for a start point as well as one or more waypoints, segmentbreaks, and an end point. Associated with each one of these GPScoordinates for the waypoints, segment breakpoints, start points, andend points would be a corresponding elevation value. The controller ortrail designer is then able to take this topographical information andcompute the distances, the average inclinations between the waypoints,and simulate a hike from this data. Thus while a hike may includevariable length workout segments as well as variable inclinationadjustments.

A programmed routine 410 is comprised of inclination adjustments anddistances for workout segments compiled by a trail designer to optimizethe selected trail exertion. For example, a moderate trail can containgrade adjustments from negative 5% to positive 20%, while a challengingtrail might include adjustments from negative 10% to positive 40% and anextreme trail can include adjustments from negative 15% to positive 60%in which some of the segments might contain drastic 20% to 30% gradechanges over previous segments. The iFit.com programs 415 relate toprograms available over Internet sites and allow a user to access a newtrail each day.

Hike simulations 420 correspond to topographically entered informationor to hike simulation inserts that may be added to the virtual trailsystem via PCMCIA, magnetic disk, PROM, flash upgrades, or other storagemeans. For example, the Grand Teton hikes displayed in FIG. 2 provide auser with a hike simulation for the Avalanche Canyon trail, the GrandTeton trail and the Teepee Glacier trail. Hike recreation 430 is dataprovided from a hike monitor worn by an individual during a normalworkout. This is an exciting feature for the hiker as it allows anindividual to perform exercise when the weather prohibits outsideexercise. In essence the monitor records the distance and elevationchanges during the workout period and provides that information to theexercise device through an interface or communication link.

Once the appropriate trail data is collected, execution block 440creates a workout hike profile. The hike development module 450 collectsinformation concerning distance, incline adjustments, and average speedtraveled. The hike development module then creates individual workoutsegments to be chained together for an overall workout profile. Blocks455, 460, 465 and 470 illustrate examples of workout segments. Workoutsegment block 465 illustrates how the grade change can occur in 1%increments. Workout block 455 demonstrates the grade 10% along with thedistance 0.05 miles. This also indicates the distance factor being 0.01miles. Workout segment block 470 demonstrates the use of a negativegrade change as well as reemphasizing the potential for 0.01 milesdistance changes. It is foreseeable that these grade changes can beadjusted to angular slopes and that the distances can be adopted asmeters or kilometers. Once the workout profile has been assembledcontaining the individual workout segments, the hike is stored inexecution block 480 for future playback on the exercise device.
